Use of aquatic plants in removing pollutants and treating the wastewater: A review

This study illustrates the importance of aquatic plants in removing pollutants and treating wastewater. Aquatic plants provide many benefits to humans, with many new applications still to be identified. However, introducing aquatic plant species that become problematic under specific conditions is putting both marine and freshwater environments at risk right now. These plant species are frequently imported from other regions for medicinal or horticultural purposes, but they eventually escape domestication and establish natural populations. Other pollutants, such as hydrocarbons and other hazardous and carcinogenic substances, can be removed from water using these aquatic plants. The application of growth-promoting bacteria that stimulate the growth of rhizosphere plants and the overgrown plants could be another modification that can have the maximum treating effect. Aquatic plants have many applications in wastewater treatment due to their much lower cost and higher efficiency. Numerous studies have proved Aquatic plants to be sinks for wastewater treatment, and they are also used in the treatment process and to reduce or limit pollutant wastewater. The treated wastewater was of acceptable quality, according to the international effluent standards for irrigation.
